Compound Search

Search for compound by name or ID

Enter a compound name, or a database identifier from this database or from an external database such as ChEBI, LIGAND, PubChem or CAS. This database may not contain mappings to all of these other databases. Partial names will generate a substring search on compound names only (not on database identifiers).
Examples: "tryptophan", "C00036"

Search/Filter by ontology

Browse the compound ontology to a specific compound, or select one or more compound classes to filter your query to only retrieve members of those classes. Note that a large number of compounds have not yet been classified, so are found under the class "an unclassified compound".

Note: Only search criteria that have been checked will be used in constructing the query. If multiple search criteria are specified, then results must satisfy ALL of them. For more search options, see the Advanced Search page. For more details on how to use this and other search facilities, see the Search Help page.
